Brumbies In early 2019, after spending over 12 months with the
Crusaders Academy, Frost was acquired by the
ACT Brumbies on a three-year deal. Although he didn't play a
Super Rugby match throughout the year, he made nine appearances for the
Canberra Vikings in the
2019 National Rugby Championship (NRC). Frost made his debut for the Brumbies in February 2020 and went on to a total of eight appearances that year. He continued to be a mainstay in the Brumbies in the subsequent years, making 42 more appearances in the 2021–2023
Super Rugby seasons. Highlights include a two-try night against the
Hurricanes in 2023. ==International career==
